Abstract：
A modified effective quark-quark interaction, which include the exchange of four kinds of field, is derived from the chiral symmetry requirement. By using this modified quark-quark interaction, the ³S ₁and ¹S ₀phase shifts of N-N scattering is studied in a RGM framework. Both the ¹S ₀and ³S ₁phase shifts are in good agreement with the experimental data, especially the ¹S ₀phase shifts are improved a lot compared with the former calculations.
